Frostbike Preview:  The Unsung Hero

We got some nice feedback on my last Design Process blog entry on the upcoming All-City seat collar, a part that I said “most people will never think twice about.”   

Let’s see how cool you think this next one is- a part we developed that I guarantee most people will never even think once about because it was specifically designed to be as minimal and as forgettable as possible:

The Double-Guide.

The part was created for the Macho Man Disc, a model designed for a fully enclosed housing system.  We chose top tube cable routing for the front derailleur of that model to keep the derailleur-end housing opening out of the mud… and because it has a seat tube barrel adjuster.  

That left two fully housed cables travelling down the bottom of the downtube.  We couldn’t find a double-housing guide available.  While it would have worked for us, we did not want to use a triple-housing guide for only two cables because, well, it’s sloppy and not as design-specific as we like to roll.

Our other option was to braze single-housing guides in pairs onto the frame.  That option really bummed me out.  The single guides we have been using are bigger than I like already.

Grouping couples of those together seemed like a really sloppy, slapped-on approach for a product that I had just developed a gorgeous dropout system for.

Plus, every time you add a brazed-on piece, you add a heat-affected zone on your tube… and more weight.

So, I asked the team super nicely if it would be cool for me to design a double guide... and they said "sure."

This guy is specifically designed to be brazed only, so the material can stay super thin (it actually weighs as much as one of our single guides).

It’s also designed to be low profile, so you only see the cable housing, not the guide.

Where is it?  

Exactly.

So there you have it.  It's pretty and minimal.  And completely forgettable.  But it's there because we thought it was really important to design it and make it for this model

The End.

So… when are these going to be available as small parts?

Nice catch, Pie Eater!  As with the Space Horse dropout (http://allcitycycles.com/blog/space_horse_dropout_development_part_3_return_of_the_dropout), we and our supplier noticed an opportunity for this part within the small builder market, so we allowed them to sell the part through their distributors. 

So, David, they are available and at your disposal already.

Great work and another reason why I’d buy one of your frame and forks. It’s the little things that make all the difference to the consumer

Geez I’m so glad I found you guys before I bought something I would be less happy with. This blog is great. I love thoughtful design with sound engineering.

Keep it up!
